Summary
Identifying new biomarkers is key to classifying asthma subtypes and improving patient management. This review explores novel markers for eosinophilic, neutrophilic, and severe asthma, aiding personalized treatment strategies.
Area of Science:
- Pulmonology and Respiratory Medicine
- Clinical Immunology
- Biomarker Discovery
Background:
- Asthma is a complex, chronic respiratory disease with diverse patient presentations and underlying mechanisms.
- Accurate classification of asthma phenotypes and endotypes is essential for effective, personalized treatment and predicting outcomes.
- Current diagnostic biomarkers, while useful, have limitations necessitating the identification of novel markers.
Purpose of the Study:
- To review recently identified biomarkers for classifying distinct asthma phenotypes/endotypes.
- To discuss novel biomarkers for type 2-high (eosinophilic) and type 2-low (neutrophilic) asthma.
- To explore biomarkers for non-steroidal anti-inflammatory drug-exacerbated respiratory disease and severe asthma.
Main Methods:
- Literature review of recent clinical trials and research studies.
- Analysis of identified biomarkers for asthma classification.
- Synthesis of information on biomarker utility in patient management.
Main Results:

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
241
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
